. Application filed September 24, 1921. Serial No'. 503,007.

lOur invention relatesto'oil'cups and for onevof .its objectsv theprovision of a simple and eflcientimproved oilcup adapted to keep theoilclean and feed the latter to vent dirt and foreign material from passinga bearing as such -oil is used. .n `A further object ofthe invention 1 sthe provision of an improved oil, cup having a wick therein to regulatethe flow ofoil from the cup. 4

A further object is the provision of simple andeflicient improved meansfor vautomatically maintaining the oil cup closed, except when beingfilled.

\ Other objects of the invention will appear` hereinafter, the novelfeatures and combina-v tions beingset forth in the appended claims.

An embodiment of our invention is illustrated in the accompanyingdrawings forming a part of this specification and ,in f

Which- Fig. 1 is a plan view of an oil cup including our improvement;

Fig. 2 is a central vertical section of the device shown in Fig. 1; and

Fig. 3 is a small elevational view of the oil cup shown in Fig. 1. y ,fn

Referring more particularly to the vdrawings, we have illustratedv anoil cup having acup proper 21 which may be of any approved shape andsize. and be yformed preferably of sheet metal. The bottom portionr 7 ofthe cup is provided with ,ay discharge passage 9 leading through thethreaded portion 8 up into the` oil yreservoir 10.r We pro-f vide a wick11 in the passage 9 so as to retard theilow of oil from the kcup and`prethrough the cup to the bearings to which the oil cup is adapted to beconnected'. Although 'our improved oil cup is particularly adapted to beconnected to bearings of a vehicle, it may have ageneral application.`Then connected to a vehicle, the jolting thereof will facilitate thepassage of the lubricant from the chamber 10 to the wick.

The bottom 7. of the oil cup may be of metal castingv provided with ashoulder 19 which is engaged by a flange 2O of the sheet y metalcover-21 which is provided with a yielding opening 22fin its centralportionin the top and in substantial alinement with the inverted cup 16.A spring 17 is located between an annular shoulder 'or seat on thetubular portion 23 and the lower peripheral I11. of the wick above thetube 23. n spring 17 presses up against the cup 16 so edge/.of theinverted cup' 16. Therspring 17 thecup 16 tight-ly against the undersideof the cover `21- so as to close the filling pening 22 against theentrance foreign materials.H p When it is desired to fill thechamber-,10

with oil, an oil can, not shown, orA otherr in strument, may be.inserted through the opens vis lpreferably of such a strengthas to holdy ing 22 ,and againstthe cup 16. Pressure is f exerted byv means of. thenozzle of the. yoil can suficient to compress the ,spring 17'so thattheoil canpass over the top of the cup 16 down into the reservoir 10.yUpon .re-

moving the oill can or other instrument from the filling opening 22, thespring 17 will Yagain compress the cup `16jup against .the cover 21 toclose the opening-p22- y,

A centralv tubular upstanding extension 23 from the circular bottom 7isiincommunication with the. discharge passage 9. The4 wick 1,1v isextended upthrou'gh the tube 23 with a portion of the wick'disposed on'the top of this tube. The invertedk cup 1 6 is therefore slidablymounted on theouter side of the tube 23 and covers the portion The astoautomatically close the opening 22.

Near the bottom of the tube 23 vare a plu- -rality-of openings 24 whichpermit the oil topass (from the reservoir 10 into t-he tube 23 and downinto'th'epassage 9 aswellas up ardly by reason of thecapillaryattraction ofthe wick 11. lWhen the cup 16 is moved downwardly to ll thechamber 10,with` oil, the cuplt presses the` portion 11 of the wick,thereby tending to squeeze the oil down intoV the passage 9 and thenceto the bearing to which 'the'oil' cup is connected. Then the oilcan orother instrument is removed fromthe the structure shown in the drawingsNorinally the spring 17 presses the bottom of this inverted cup againstthe opening 22 so as to close the same7 thereby keeping dust sageway 9andto suck the oil up along to# .Ward the upper en'dof the Wick when thepressure"onth'einverted cuplis released. Fur-` i "thernioreftliewiclracts asa iilter'to kprevent any grit orforeign material in the oil fromlreaching the bearing to be lubricated.
